'Son's' in the Bible

The nakedness of your son’s daughter or your daughter’s daughter, their nakedness you shall not uncover; for their nakedness is yours.

You shall not uncover the nakedness of your daughter-in-law; she is your son’s wife, you shall not uncover her nakedness.

You shall not uncover the nakedness of a woman and of her daughter, nor shall you take her son’s daughter or her daughter’s daughter, to uncover her nakedness; they are blood relatives. It is lewdness.
